it is called classification
hope this helps :)
Ion is e
Element is a
Compound is f
Sorry that’s all I know
A ) v = 567 - 33 = 534 km/h
v = d / t ⇒ t = d / v
t = 780 km / 534 km/h = 1.46 h
b ) v = 567 + 33 = 600 km/h
t = 780 km / 600 km/h = 1.3 h
c ) v = (567² +33²) ^(1/2) = √320,400 = 566 km/h
t = 780 km/ 566 km/h = 1.378 h
The speed of electrons striking the anode is increased, the density of the emitted x-rays increases.
Answer: Option 2
<u>Explanation:</u>
Whenever electrons are made to be incident on any anode, they will be interacting with the surface atoms of anode. So these interaction will lead to excitation of electrons of the surface atoms of the anode.
Thus when the excited electron will come back to ground state, it will emit x-rays. Thus, on increasing the speed of the striking electrons, it will gain the property of interacting with larger amount of surface atoms leading to increase in the emission of X-rays .
Thus, this increase in the emission of X-rays will lead to increase in the density of X-ray. So the speed of electrons striking the anode is increased, the density of the emitted x-rays increases.
